Message

At TeamsWell, I deliver end-to-end features for a storefront marketplace and help migrate legacy FileMaker processes into a custom in-house ERP. I’ve also automated processes with AI and generated over 90% E2E code coverage for new features.

At AgendaPro, I developed features for the AgendaPro mobile application, refactored modules, and contributed to the migration from a monolith to microservices using a Backend-for-Frontend architecture. I applied testing and observability practices to reduce production bugs and monitor errors.

Earlier, I developed web and mobile applications at Koibanx, Applaudo Studios, and Vincu Hub, including Web3 applications and features for the Multimoney app. My work has included React Native, React, and backend services, as well as production releases for iOS and Android.
